IMPROVEMENT IN STEAM-RADIATORS.

Specificationforlning part of Letters Patent No. 175,24 I dated March 28,

1876 application filed March 4, 1876.

.To all whom. it may concern Be it known thatYI, JOHN O. COPE, of' Philof Philadelphia and State of Bennsylv'ania, have invented certain new'and usefullmprovements in Steam-Radiand I dofhereby declare that andY exact descrip use'- the same, reference being had tothe companying drawings, land to the letters `of of this specitcationgl u My invention relates to that class of steamradiators'where the radiator is placedV in the cellar or lower part ofthe building, and the heated air carried.-` through pipes or flues through thebuildingghand the nature ofmy invention vconsistsfinfthe `construction and innfter more ,f1-illy set forth.` 4

The o penil'ig in 1 the 'ground-` joint end of the` half return-bend is alittle oblong in the direction of the pipe to which it is attached, to admit a full Iiow of steam in case of .any variation in length ot' pipe, The boltholes are also made oblong or elongated, and parallel with the hole in the return-bend. The pipe E is made of cast-iron, in sections, so that the heater may be enlarged without disturbing the part already built. 'Ihis pipe is, on its under side, provided with short necks a at suitable intervals, and each'neck iitted with a flanged ground joint, to correspond with the anged joint of the hal-f returnbend, which forms the cpnnection with the .first ron7 of pipes G. The pipe E Lhas also a anged ground `)oint at "each end, to` which another section ofthe heater nm'yghe added. The'pipe E at the bottom is precisely.' similar, except that the necks areon the upper instead of the under side.

what I claim as new, and desireto'sevcure `by Letters Patent, is-

In vtestimony that I claim the foregoing as. my own I aiix my signature in presence ot two witnesses.
